Dynatrace SaaS release notes version 1.274

Rollout start: Aug 29, 2023

Breaking changes

Fixed data types of Grail fields for DAVIS_EVENT and DAVIS_PROBLEM events

Breaking change

We have fixed data types of Grail fields for DAVIS_EVENT and DAVIS_PROBLEM events.

This is a breaking change for string-specific DQL functions (for example, == "…", contains, startsWith). Use toString(...) to fix the behavior.

Newly written records use these types:

If you use DQL functions that only work with string data types, you need to do a toString(...) before that so that it still works.

For example, change this:

| filter dt.davis.is_frequent_event == "true"

to this:

| filter toString(dt.davis.is_frequent_event) == "true"

There are also other options, but adding toString(...) to a changed field name will fix every query.

Announcements

Thresholds API sunset

With the release of Dynatrace version 1.275, we will turn off the Thresholds API. Any requests to these endpoints will stop working. Migrate your automations to the Settings API instead. For more information, see the migration guide.

New features and enhancements

New matcher attribute in log storage configuration

Infrastructure Observability | Logs

Now you can use Log record level attribute in log storage configuration:

• Log Management and Analytics
• Log Monitoring Classic

New DQL keyword

Platform | DQL

Now you can use the in keyword in your DQL queries as a comparison operator.

New DQL functions

Platform | DQL

Now you can include the following functions in your DQL queries:

• arrayConcat
  The arrayConcat function concatenates multiple arrays into a single array.

View the origin of vulnerable libraries

Application Security | Vulnerabilities

You can now view the origin of a vulnerable Java software component on the remediation tracking for process groups and processes affected by a vulnerability.

For example:

For information on how to navigate there, see Remediation tracking.

Unified services for trace ingest

Application Observability | Services

We enhanced support for OpenTelemetry and cloud-native monitoring with a new service type, Unified service. Unified services are based on OpenTelemetry spans ingested via the ingestion APIs and provide

• Automatic baselining and Davis® AI integration
• Automatic endpoint detection
• New service metrics, such as response time, throughput, and failure rate
• Advanced horizontal topology detection
• Support for custom application metrics and application logs
• Agentless support for Istio service meshes
• Opt-in endpoint monitoring with new metrics

To get started, see Unified services.

Detection attributes highlights

Application Observability | ServicesApplication Observability | Databases

Attributes used for detection are marked with an asterisk ✱ on the service and database, under Properties and tags.

Davis problems refresh rate

Platform | Davis AI

We now refresh Davis events and problems in Grail every 6 hours for as long as they're not closed. This guarantees query results for problems/event snapshots by querying 6-hour timeframes.

Unified analysis screens for Kubernetes nodes

Infrastructure Observability | Kubernetes

You can now access new unified analysis list and detail screens for Kubernetes nodes.

Advanced Kubernetes label filtering

Infrastructure Observability | Kubernetes

You can now apply multiple values simultaneously in the Kubernetes label filter.

Detailed OneAgent status in unified analysis host page

Infrastructure Observability | Hosts

The Properties and tags section of the unified analysis host page features a OneAgent status:

• The status can be either active or inactive, along with a reason for the status.
• Detailed status information is available for up to 24 hours. Beyond that, the status will default to inactive.
• An unknown status will be displayed if data is unavailable.
• The status may be delayed by up to 5 minutes.

RKE2 technology grouping

Infrastructure Observability | Hosts

We've added RKE2 technology per PGI. RKE2 Agents and RKE2 Servers are now grouped into separate process groups.

High System Load events trigger process instance snapshots

Infrastructure Observability | Hosts

High System Load events will now automatically trigger process instance snapshots.

The 1.274 GA release contains 13 resolved issues (including 1 vulnerability resolution).

os agent

• Vulnerability: Improved security by updating the aiohttp package to version 3.8.5. (HOST-3456)

Cluster

• The action validation in extension is now stricter to avoid incorrect error messages. (TI-7825)
• Fixed metrics malfunctioning when more than a certain threshold are created. (CLUSTER-7919)
• Fixed VMware credentials state button. (HOST-3466)
• We disabled obsolete custom process monitoring rules, fixing the issue in which it was impossible to delete them. (HOST-3507)
• The status of problems that receive updates after resolving is now UPDATED instead of RESOLVED. The RESOLVED status is now unique between the previous and succeeding records for the same event ID. (DAVIS-5443)
• Added extensibility to the new service UI. (TI-7916)
• Fixed data types of Grail fields for DAVIS_EVENT and DAVIS_PROBLEM events. Newly written records use these types: * event.start: string -> timestamp * event.end: string -> timestamp * resolved_problem_duration: string (in milliseconds) -> duration (in nanoseconds) * dt.davis.timeout: string -> long * dt.davis.is_frequent_event: string -> boolean * maintenance.is_under_maintenance: string -> boolean * dt.davis.analysis_time_budget: string -> long * dt.davis.analysis_trigger_delay: string -> long * dt.davis.is_frequent_issue_detection_allowed -> boolean * dt.davis.is_merging_allowed: string -> boolean * dt.davis.is_problem_suppressed: string -> boolean * dt.davis.is_entity_remapping_allowed: string -> boolean This is a breaking change for string-specific DQL functions (for example, == "...", contains, startsWith). Use toString(...) to fix the behavior. (DAVIS-5452)
• Fixed an issue where problems that were directly impacting the host were not displayed on the host page problems tab in a timeframe that the problem was present. (HOST-3493)

Synthetic monitoring

• Fixed an issue with validation of credentials in a customized script of a browser monitor on-demand execution. (SYNTH-6024)

User interface

• We now display errors from thrown by the execute endpoint. (EXA-7365)
